パキポディウム･グラキリス(pachypodium gracilius)

実生のグラキリス、5年目になって少し丸くなったみたいです。丸くなるのには年数が要るのでしょうか。前列は1年若い苗です、今年は少し丸くなるでしょうか・・・ Seedling gracilius. It has passed few years since germinate, become looks like roundly. Is it need some years to make round shape? Seedling that front row is 1 year younger than back. Will younger one become roundly this year?
